I have the Mijia bedside lamp and use Yeelight to control it. For the first day, it worked fine, but then it suddenly didn't let me control anything anymore and disconnected. I can reset it and - sometimes - I can get it to work for a little while (anything from 1 s to 30 min), sometimes I cannot reconnect at all. It is all on a 2.4G network, and I can see the "yeelink device" on the wireless router when it is connected. I tried reinstalling the app, but this did not help. In MiHome, I cannot find the lamp at all. My phone is on Android 7.0.
Could you please advise on this problem. I have sent you feedback on the app but not heard back yet.
